Understanding C++ operator precedence and function calls
This is an easy C++ question that tests your working knowledge of operator precedence and how function calls interact with other operations. It's the kind of question designed to catch candidates who skim code rather than read it carefully—a practical skill in any technical interview.
To answer correctly, you need to trace through the order in which operations execute. C++ has well-defined rules about which operators bind tighter than others, and understanding those rules is essential when reading unfamiliar code or debugging subtle bugs. The question rewards precision: small details in operator precedence can completely change what a line of code does.
